That car runs on a form of biodiesel, not water:
"You still can’t pour water into your fuel tank and run your engine on water power, but Audi has just opened a pilot plant in Dresden, Germany, that is producing biodiesel from a process that uses water, carbon dioxide, and green power. The resulting substance is being called “blue crude,” and when it’s refined, it behaves just like regular diesel fuel. In fact, it’s so similar to diesel that Audi is able to put it directly into an A8 TDI without a problem."
Do you think any auto company will come up with an engine that runs on pure water?
Do you think in the future you can buy an inkjet printer that will print more than 10 pages on factory fitted cartridge?
do you ever wonder why a printer cost $40 while the Cartridge cost $60.
